Privacy Policy

Last updated: 12 August 2026

Tokkucal ("we", "us") provides free online calculators and utility tools at this website. This policy explains what data is involved when you use the site and why.

No account, no stored calculations

Tokkucal does not require you to create an account or log in. The numbers you enter into a calculator, and the results shown, are not saved to a database or linked to you in any way.

Image and QR code tools

Images uploaded to the Image Compressor or Image Resizer are processed in memory on our server and returned to your browser in the same request. They are never written to disk or kept after the response is sent. The QR Code Generator runs entirely in your browser — the content you turn into a QR code is never sent to our servers at all.

Contact form

If you use the contact form, the name, email address, subject and message you provide are sent to us by email so we can respond. This information is not stored in a database or used for marketing.

Cookies

Tokkucal uses a session cookie to keep the site secure (for example, to prevent cross-site request forgery). This cookie does not identify you personally and expires automatically.

Analytics and advertising

We may use Google Analytics to understand overall traffic and which tools are popular, and Google AdSense to show ads that keep Tokkucal free. Both may use cookies or similar technologies to collect information such as your approximate location, device type and browsing behaviour across websites. Google's use of this data is governed by Google's Privacy & Terms. You can control ad personalisation through Google Ads Settings.

Server logs

Like most websites, our server automatically records basic technical information for security and troubleshooting purposes — such as IP address, browser type and pages requested. These logs are used only to keep the service reliable and secure, and are not used to build a profile of individual visitors.

Children's privacy

Tokkucal is a general-audience utility website and does not knowingly collect personal information from children.

Changes to this policy

We may update this policy from time to time. Changes will be posted on this page with an updated date.
